Product Overview


Product Description

Plate corundum is a kind of pure sintered corundum without adding any additives such as MgO, B2O3 and so on. It has a coarse crystal structure and well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99%. Lamellar crystal structure, with small pores and many closed pores, the porosity is roughly the same as fused corundum, with high purity, good volume stability, minimal reburning shrinkage, and good thermal shock stability and bending strength after high temperature treatment of refractory materials or castables used for production, but the price is higher than other alumina.
Tabular corundum can be as the main ingredients used in magnesium aluminum carbon, carbon, carbon, magnesium, magnesium aluminum spinel, aluminium chrome brick, also can be used as an enrichment of alumina composition is introduced into the high alumina monolithic refractories, can be widely used in steel, foundry, ceramic and other industries, the application in the steel industry almost covers the whole process of ironmaking steelmaking.
